Need help finding source of crash

@Starscream195 

Move your Mods folder to the Desktop and delete localthumbcache.package. Then test the game
If it works now check for updates to your Mods and CC. Add it back a little at a time while testing until you have found all that are broken.

@Starscream195 Please post your computer's dxdiag - how to get your dxdiag and attach the txt file to the paper clip in the lower right corner of the forum response window.

@roberta591 Sorry for the really late response, but here it is!

@Starscream195  Random crashes are hard to pin point the cause. The dxdiag looks good. The dxdfiag is giving some errors though. Is Windows up to daste? Is this a new computer? That video card requires a minimum 650W power supply. Is there plenty of air flow? Is this a scratch build computer? Have you tried a bench mark program like 3dmark - there are free versions?Please post the make and model of the power supply.

@Starscream195 There should be a label some where on the side of the power supply listing all the specs. The only thing I can suggest is removing all the mods and start a new game and see if it crashes. If the game now plays then its probably a mod or a mod conflict. I once had a computer tyhat would crash once and then run fine for the rest of the day. Traced the problem to a bad memory module. T replaced the module and no issues after that. It took me a couple of weeks to figure that out. At the end of the dxdiag I will find errors. Windows keeps an error log that may help but many times iy only provides clues to the issue. You didn't say how new this computer is.

@Starscream195  A prebuilt computer should have a power supply that's technically sufficient for its hardware.  You might run into trouble if you overclocked the components, but in that case  you'd probably have figured out the system was unstable when testing the overclock.  The other possibility is a faulty PSU, but that typically doesn't look like the crashes you're describing.

Your dxdiag shows access violations from Sims 4.  These mean that the game tried to access a memory address in an improper way, although none of the crash info would ever tell you what function in-game was the culprit.  These kinds of errors can in theory be caused by hardware issues, for example a bad memory module or failing hard drive, but in the absence of any other indicators of hardware problems, and your info doesn't have any, it's much more likely that this problem is confined to Sims 4, and in particular your mods or possibly your custom content.

I understand the crashes are infrequent enough to make testing your mods and cc difficult, but one thing that would make it easier is if you could find at least one crash that was reproducible.  To that end, try saving often, I mean extremely often, so there's a good chance the same event that causes a crash once is about to fire at one of your save points, and you can load it over and over to test.

Another potentially useful approach is taking your lastexceptions, if you have any, to the MCCC Discord and asking for help.  The server has bots that can read your files and provide a likely culprit, and the support people can take a closer look if necessary.  They might be able to tell you that a particular mod is responsible even without the crashes being reproducible.

@Starscream195 Some power supplies are more reliable then others and some do NOT supply enough power on the +12V for the video card. Others have two +12 rails that only supply so many amps per rail. I have seen power supplies with dual rails hooked up with too big a load on one rail. This could cause the voltage regulators to fail and then heal. I have seen power supplies boost specs for other values to maintain the wattage figure. It could be the cooling fan can't handle the heat when the power supply is under full load. Not all power supplies are created equal. Memory modules can and do go bad. Random and infrequent crashes are hard to diagnose. There are others errors in the dxdiag that does not eliminate a hardware issue.The hardware looks to be good but... Have you checked to see if there are any Windows updates? Maybe running a test program like 3dmark (there is a free version) a few times and see if that runs error free.
